Troubleshooting intermittent fault in an SRS SR530 reference oscillator PLL

[timeandfrequency]

Hello DaJMasta,

Glad to read that the TE is finally repaired.
As I mentionned in a former post, some design choices made by SR are a bit questionable.

It is also true that an old PCB tents to absorb humidity which favors leakage .
Set the kitchen kiln to 50°C and 'bake' the board for 6 hours sometimes restores the isolation resistance between tracks.
